This item is used, in very good condition, Unit works, sold as-is, no returns ●CG-931: NTSC Color Pattern Generator in compliance with EIA (RS-189A) and SMPTE (ECR-1-1978) Standards The CG-931 can output color-bar signals in compliance with both RS-189A and ECR-1-1978 standards. In addition to the field color bar signals, it can provide patterns including I/Q/W ON/OFF switching, color bar signals without luminance component and gray scale signals without chrominance component instantaneously. ●* The following are common features for the 2 models.S-Output An S-output is provided as standard. In addition, Y S and C outputs are provided at the rear panel (BNC connectors), and the output levels of each are variable individually ●Variable Setting Levels The setup, chrominance and luminance levels are arbitrarily settable and a calibration signal is provided for each, as a convenience in making simple adjustments and repairs to color TV receivers. ●Individual Rasters for Purity Adjustments Red, blue, green and white rasters are provided for use in verification of purity and in adjustment and inspection of white balance. ●Dot and Cross-Hatch Patterns for Adjustments of Linearity and Convergence A central dot can be used for adjustment of picture tube static convergence, and a cross-hatch pattern can be used for adjustment of dynamic convergence, these being provided as a convenience in adjusting vertical/horizontal amplitude and linearity. ●Center Cross and Dot for Convergence Adjustment A center cross and dot are provided to enable adjustment and inspection of raster alignment and convergence. A white window on a black background enables testing high-voltage stability. A video output for monitor TVs (75Ω) and RF output for TV receivers (75Ω) are provided as standard. To simplify the task of observing the video signal on an oscilloscope, the vertical and horizontal sync signals are provided as outputs. In addition, the sync signals include equivalent pulses and their phase is locked to the subcarrier frequency. ●Interlaced and Progressive Scanning In addition to the normally-used interlaced scanning, progressive scanning is also possible, thereby reducing jitter in the horizontal lines of the center cross and cross-hatch patterns. ●RF Output ON/OFF Switching When using only the video output or when it is desirable to eliminate interference, the unwanted RF output can be switched off. While the standard RF channels of the CG-931 are Japanese channels and those of the CG-932 are European channels, they can be switched to the frequencies of other major countries, such as the US channels with the CG-931 and the Italian, Australian, New Zealand and UK channels with the CG-932. ●Remote Control Capability With each model, the remote switching of patterns using an optional remote control unit (RT-62A) is available as a factory option (made to order.) 16×20 (white on black background including one dot at the center of the screen) 1×1 (white on black background with cross at the center of the screen) 15×19 (white on black background) 0.5×0.5 (white on black background) SMPTE: Conforms to EIR-1-1978 75% intensity sequential PAL color bars; bar 1 (divided in two) & bar 2 (divided in three) For the color signal‚ Q and I (U‚ V for PAL) at the bottom of the screen. Instead of 100% white and black‚ a full-field color bar is inserted at the top of the screen. The chrominance component is eliminated from the color bar signal and the pattern is provided with luminance only. The luminance component is eliminated from the color bar signal and the pattern is provided with chrominance only. VAR: 0 to 1.5Vp-p (75Ω load) CAL: Y S‚ 1Vp-p (SYNC to 100% white)‚ C 286mVp-p (burst)‚ 300mVp-p (PAL only) Horizontal and vertical frequencies Minimum of 8 cycle at the back porch of the horizontal sync signal The color bar or raster chrominance level is adjustable approximately ±20%. However‚ the yellow and cyan color bar signal amplitude maximum value can be preset to the same level as the 100% white signal. The luminance level of patterns is adjustable approximately 20%. However‚ presetting of the white signal level for the raster to 100% is possible. The setup level of patterns is variable 0 to 10%. However‚ presetting of the black level to 7.5% is possible.
